Applying this logic, perhaps we can get "professional" stock ... manipulators off the TV. CNBC can go away entirely. Marketing speak would be replaced with value charts. Ban all forums that discuss specific stock values.
Then prevent people from buying stocks in groups. Mutual funds, ETFs, etc... all of these abstractions on abstractions, we can throw them away. The more abstractions we throw away, the closer we get to what all this should actually be meant to serve; people.
